ATTACHMENT FOR COMBING MACHINES.

Application filed June 10, 1927. Serial No. 197.907

My present invention relates tocombing machines, and is particularlydirected to a' selvage guide for the detaching rolls of such machines,and has for its object the provision of a rigidly secured guide for eachside of the machine that flexibly engages the roll a little above thecenter thereof to guide the cotton the notches having its outer edgesrounded to form a guide, the vertical arm of the plate receiving thereinbinding means for a verti callyadjustable angularly disposed wiperholder removably supported on the said vertical arm of the sup-port thatcontacts with the detaching roll of the machine.

The drawings illustrate a satisfactory embodiment of the improvement andwherein:

Figure 1 is a view illustrating my inven tion in applied position.

Figure 2 is a perspective view of the 1mprovement.

Figure 3 is a front elevation thereof.

Figure 4 is a planview of the blank from which the holder for theleather wiper strip is formed.

In Figure 1 of the drawings, the improvement is disclosed in appliedposition upon the type of combing machines known to the trade as the Whitin and Nasmith machine. As the constructions of these machines arewell known in the art, a detail description thereof and the working ofthe parts constituting the same is not believed necessary. In thedrawings the comber cylinder is indicated the numeral 1, thebottomnipper plate by the numeral 2 and the bottom detaching roll by thenumeral As my improvement is designed for contacting engagement with thedetaching roll 3 to serve as a guide for the cotton selvage therefrom,and as the construction and operation of this type of machines, as abovestated, is well known in the art, reference to the remainder of themachine is not believed necessary. 1

It will, of course, be understood that one of these devices is placed ateach side of the machine with the wiper parts ofthe two devices engagingthe end parts of the detaching roll 3 but asthe devices are of the sameconstruction but one of them will be described. Each device comprises aframe or support composed of a rectangular metal. plate whose horizontalportion is indicated in'the draw ings by the numeral 4and whoseverticalportion by the numeral 5. The horizontal'porlongitudinal slot'6and through thisslotthere is passed a bolt member 7 engaged'by a nut 3which holds the device on the comber. The vertical arm 5 of the supportis notched, as at 7, and upward of the notch the outer edge of the armis rounded, as at 9, to provide seltion 4 from the end thereof is formedwith a vage guides. The notch enables the edge to ibe bentinto roundedshape. The angle-or vertical arm of the support, inward of the notch 7is provided with spaced aligning somewhat elongated openings 10, andpassing through these openings there are the shanks of short headed.bolts 11 screwed through openings 12 in the depending plate or skirt13of a holder member 14. As disclosed by Figure 4 of the drawings, theholder member 14 may be constructed from a substantially T-shaped stripor member, and the upper portion thereof is bent over the body in a linewith its lower edge, and the projecting portions are then bent uponthemselvesand extended inwardly over the rightangular part 15 of theholder thus provided. This right angular portion 15, with its bendablelower portions or arms 16 afford a pocket for a leather strip'17, andthis strip contacts with the roll 3 at a point above the axial centerthereof. The holder 14 is constructed of some suitable strong metal,as'is the frame or support thatconstitutes the right angular arms 4 and51' The leather wiper member 17 is at all times in contact with theperiphery of the roll to effectively wipethe rolland to direct selvagetherefrom over the port.

The simplicity of the improvement and the advantages thereof will, it isthought, be perfect-ly'apparent to those skilled in the artto which suchinvention relates, itbeing obvious that the support is adj ustablysustained upon the comber and that the holder 14 is likewise adj ustablysustained upon the support. When in operation the device affords a rigidstructure and will effectively prevent'the selvage guide flange 9 of thesupwinding around the roll and stop the operation of the cornber.

Having described the invention, 1 claim 1. In a comber and incombination with the detaching rolls thereof, a support comprising arightangular member having its horizontal arm adjustably but rigidlysecured. on the frame of the comber, a holder removably and verticallyadjustably secured on the vertical part of the support, and a leatherstrip designed to be received in and supported by the holder andengaging one of the said rolls.

2. In a coniber machine and in combination with the detaching rollsthereof, a support ing member oi rightangular shape whose horizontalpart is of agreater length than its vertical part and which horizontalpart is provided with an elongated slot for the reception of securingmeans, the vertical part having its outer edge notched and the cornerthereof above the notch rounded to provide a guide said vertical parthaving spaced elon gated openings therethrough, bolts having threadedshanks passing through the openings, a holder comprising a pocket havinga rightangular shirt on the inner edge thereof and through which thebolts are screwed and said holder designed for the. reception of aleather wiper member which engages one of the rolls.

3. In a comber machine, and in combination with its detaching rolls, asupport connected with a part 01 the machine and extending between twopairs of said rolls, said support having a guidingpart thereon, a holdervertically adjustable on the support below the guiding part thereof andhaving a horizontal part and a wiper member of flexible material carriedby said horizontal part and engaging one of the rolls.

In testimony whereof I afiix my signature.
